which is mounted upon the rotating shaft-12 move freely longitud inally.` i Said sleeve- 28 has a hole near its lower end. throughwhich is' inserted the pin 29, so as to extendl through the side walls of said sleeve 28 and through a slettedppenmg in the shaft 12 toinsure y the rotation of the sleeve -28gthroughv-said shaft 12`and.to permit longitudinal ,Inovement of said sleeve 28.. 31 31 are radial slots in the .projecting portions of the sleeve 28 and are of proper width to receive the ends of the pins 27,;js`o.- that any movement 'up' and 4down of the'outer end of said weights 25 -would cause the sleeve 28 to move longitudinally onthe shaft 12 and the pins 27 27 to i slide in and out in the slots 3 1y 31. The plate f5 has a hole in its central portion adapted to have mounted therein the sleeve 32,-the upper en d of-'whch is screw-threaded tosecure the bearing 39. Said sleeve 32 extends downwardly, as shown in Fig. 2, and has at its lower end a. slot 33.

therein the nut 34, .which is threaded at its4 1 upper-end, its lower endv having threaded therein a'screw 35 whichextends outwardly through the slot 33, the p in 35 and the slot'33 being s'o arranged as to prevent the nut 34 from'revolving'in' the sleeve 32, but to permit it to move longitudinally therein. ,40'

Fitted into the lower end of said nut 34 is a plug36, the lower surface of which is ilat. 37 is a hich is inserted in a hole in the shaft 12, 1 `pointed en'd bearing'a ainst the lower surface of the plu@r 36 and its ower end against the pin 29, so th movement of the sleeve 28 wouldj'be communicated tov thepi'n 29, thence t 'ithe pointed 'pin 37and the nut 34 througli',. the plug36. 38 is a; spindle'having a sharply-inc ined threaded portion adapted to loosely fit in the threaded portion of the nut 34, so' that a longitudinal movement of the nut 34 will `revolve l -.the spindle 38. Said spindle 38has abearl ing inthe screw-collar 39, which bearing may be jeweled, if found desirable, so that the pin 38 willfrevolve' therein with as little friction as possible. The spindle 38 has secured thereto the collar 40, towhich is attached the inner end of a convolute spring 41, the outer -end of said spring being attached toa stud 42,-which in turn is'secured in the plate 4. 43, is an adjusting-lever which is mounted upon the upper end of the sleeve 32 in a manner to revolve around the same. Said lever 43. has a hollow shell 44 secured therein which mfsuch manner' as to rotate'therewith andA It also has mounted at anyflongitudinal -litted'to enmesh with the Worm 23, so that when said worm 23 is revolved it will revolve` the shaft 8 and the odometer mechanism to e tension ofsaid spring 41 by register the' distance traveled as communicatedby the rotating parts of the speed-indicator. 47 is a sleevwhich is threaded into. the side of the casin 1 and has mounted to revolve therein a sha t 48. Said shaft 48 has aflattened portion 49 on its inner end and a -round ca. 50 on its outer end used to revolve said sha t 48. f 51 is a plug mounted in the disk 5 in such manner as to be free to move longitudinally. Said plug 51 is arranged to press against the bottom of a spring 52,which spring is secured to the disk 5 by the screw 53, its inner end being adapted to press against the under side of the collar 40. Said collar 40 is mounted on the spindle 38, the parts49 and 51 being so arranged that by revolvin the circular cap 50 the plug 51 wil be presse upwardly and press against the spring 52, thereby causing the inner end of said spring 52 to. press a amst the collar 40 to hold the pointer i'n W atever position it may be in when the shaft 48 is revolved.

lThe object 0f the locking devicajust described is that when it is desired to keep a more or less permanent record of such s eed the ca 50 may be turned to lock the pointer 45 at t e graduation indicated and cause it to remain there until the spring52 is released by Fig. 1.

more or less tension on the shaft 38 by mov- `ing the lever 43 toward the center end of the spring, thereby reducing the number of con-v 'volutions of the spring between the point where it is attached to the shaft 38 and the point where it passes through the slot in the hollow stud 44. The lever 43 may be held in its adjusted position' by filling the hollow portion of the stud 44 with sealing-wax. This insures the permanency of the adjustment as well as the instrument against being tampered with to throw it outof adjustment.

In practice when used as a speed-indicator for automobiles theinstrument 1s attached to the dashboard or any other convenient place on an automoblie and connected by a flexibleshaft 54 with the hub of one of the wheels or any other revolving part of theV automobile' from which .thc s'pced traveled may be taken.

Fig. 6 represents a modified form of my he spring 41 may be adjustedto givev lturning the cap 50 to the `position shown inv ISO 1s identically Athe same ias is shownin .1

wise of the instrument would not change. the )position of the Weight-arms' or of the longitudinallymovinv parts `referred t-o owing toits gravitational balance.. The upper parts ofv the weight-arms 25 are thrown outwardly by the force `due to the -revolving of the sha-ft v12. The outward movement of vthe outer 'ends of said weights 25 is oount-erbalanoed by the tension of the spring 41 exerted through the shaft 38, the screw-threaded por-tion at its lower end, the nut 34, the pin 37 pin 2.9, `and thes'leeve 28.-

The opera-tion of` myimproved speed-indi- -cat-or is as follows-z I Will first refer tothe position of the rparts as indicated in Fig-1. The parts of the indicator as shown in full 'lines .illustrate their position 'When the instrument is at rest. This shows the vWei htfarms 25 moved upwardly and nearly para lel'With the shaft 12 through the tension of the spring 41. "When my speed-'indicator is to be used to measure the speed 'at which an automobile is traveling, the shaft 12 of the speed-,indicator will be so connected tof t-he revolving parts of i the automobile as t revolve at a speed proportional to the c tameter f its Wheels. From this proportion `the graduations on the dial of the speed-indicator maybe calculatedso as to measure the rate of speed per minute or per hour at which the automobile is traveling. Upon revolving the shaft 12 from'the moving part of an automobile to which it is connected the sleeve .28 and the weight-arms -25 will be Caused to revolve, .and as the outer .ends are considerably heavier than the inner ones the Centrifugal force will cause, the outer ends to move outwardly and the sleeve 2S lto move upwardly through the pins 27 and slots 31, thereby moving the Apin 29,
